TOGGLE FOR CRUSHERS Filed Aug. 16', 1941 within one each of two ribs 1.

Patented July 27, 1943 f 12,325,195 1 f 1 l f froGeLs iron oR snERs v "ltdtvard ltetersom'Readingt far 'A'ppIication gustus, 194i, seal No. 467,195 l .-.;fr1;o1aim; (onse -{53) V The invention relates to the art of toggles.

One purpose of the invention is to provide toggles with removable and replaceable ends.

A further purpose is to construct toggle bodies with bifurcated edges at the ends and to hold removable end bumpers or wear parts within the bifurcations by fins or tongues fitting therein and riveted to place, whereby the fins or tongues are supported by the side walls against tilting in either direction.

A further purpose is to provide toggles with removable bufizer or wear strips along the ends in the form of beads held within forked end edges and having shoulders abutting the outer limits of the forks to support against tilting.

A further purpose is to hold a toggle bufier or bead by a fin between spaced, inwardly springpressing forked end strips and to provide end ad justment by shims between bead shoulders and outer faces of the end strips. r

A further purpose is to provide bead buffers for the ends of toggles, having shoulder thrust lengthwise of the buffers, to secure rigid support against yielding lengthwise, and to adjust the lengths of the-beaded toggles by shims between V the shouldes and the end edges of the toggle body.

Figure 1 is a top plan view of a preferred form of toggle.

Figure 2 is a cross section 2--2.

of Figure 1 upon line Figure 3 is a cross sectional perspective of the ment of the entire toggle or have bee-n built up of parts which lacked rigidity and were not capable of adjustment. It is the purpose of the present invention to provide a toggle having removable end beads to take end wear and capable of lengthwise adjustment, the beads being securely attached and yet easily replaceable, and the en.-

. tire structure being rigid in all adjusted positions. a o r I The body 6 of the crusher toggle shown is re-- inforced by longitudinal ribs 1, 8, 9, l0 and by transverse ribs ll. Lifting rings l2 are cast,

The end edges I3 of the body are grooved by he.mambead I at IE but whose inner walls are finished desirably along theiroppositely facing inside surfaces at l6 and H and at l8and [9 outside (considered with respect to the length of the toggle) of a row of rivet or bolt holes transverse to the toggle.

It will be evident that each groove divides the movablebufiers takingthe wear atthe ends of the completed toggle. The beads carry inwardly facing'shoulders' 24 to engage the end surfaces 2|, or to engage shims used for adjustment purposes and located between the outwardly faclike ing surfaces 23 and the inwardlyfacing shoulders 24. r 7

Between the shoulders 24 the tongues 22 extend inwardly from the buffers and are of such thickness as to bedrive fitsbetween the finished inner walls IS, I1, 18 and=l9 of the strips or fins. The grooves are made deep, considerably beyond the inner tongue edges so. asto provide ample follow-up of the resilient strip pressure against the tongues. The side pressure of the strips is effective both to reduce the tendency of the v tongues to move within the grooves-and hence to wear-and to maintain adequate side pressure notwithstanding wear. 7 v

The tongues are provided with rivet holes 26 in line with the rivet or bolt holes 20 and elongated lengthwise of the toggles to accommodate adjustment of the beads.

Preferably the toggle bodies and the buffers are held in place by rivets 21 passing through therivet holes in the tongue.

put in position about the tongues attached to the buffers and the tongues are inserted to a position a where a shim or the shims is or are gripped be- I tween the shoulders 23 and 24 and surfaces 2|, or, in the absence of shims, the shoulders direct 1y engage tightly against the outwardly facing surfaces 2| at theshortest limit of length ad-g and 29, in order to accommodate the transverse end portions 30 and 3! of shims 25, seen in Figures5and6. r v The deep grooving of the'edges gives a correspondingly highly resilient spring side grip l6 at heir {inner ends In assemblage any shim or shimsrequired are and ll, of the edges l8 and I8 against each 7 fto others skilled in the art, to obtain all or part tongue between them, holding the tongues initially and helping to hold them additionally to the clamping hold effected by the setting of the belts:

of the benefits ,of my invention without; copying the structure shown, and I, therefore, claim all such inso far as they fall within the reasonable 5 spirit and scope of my invention.

- Havingthus described my invention, what I claim as new and desire to secure by Letters Patent is:

A unitary crusher toggle'body having grooved edges with 'riv'j'etfas'ten'ings tightening the edge 10 end, edges providing spaced resilient edge strips strips upon a" bead tongue between them and with a range of adjustment longitudinally which cooperates with the type of construction used; The construction is rugged and rigid and the beads are quickly and easily replaceablei'" The present application is a continuationiin part of my application for Toggle, Ser. No. 267,-

440 filed April 12, 1939.

In view of my invention and disclosureyaria i tions and modifications to meet individual whim or particular need will doubtless become evident and outwardly facing endedge surfaces, beads for the edgeshaving'inwardly directed tongues,

each resiliently held between two strips and inwardly'facing shoulders adjacent the edge strip Li'surface and adapted to engage them, a shim surzrounding a'tongue and fitting between the shoulders and the adj oining surfaces, and fastenings 'extending'through'the strips and tongues and v holdingithe beads to the body.
